If you never heard of LEGO Dimensions before you have no clue what you are missing, you get to play with characters you never thought you could see in a LEGO game together, using vehicles and weapons you never thought possible. I mean really who would have thought Scooby Doo would be able to ride in the GhostBuster car! lolEach pack adds more fun to the game, it is a game that never gets old because you can just keep adding on level packs.The GhostBuster pack includes: Peter Venkman, Ecto-1 and Ghost Trap. They were pretty easy to put together. I like that there is 2 ways to play the kiddos get to have fun putting their guys together and once together they get to play with them!! This is only ONE of the many level packs! To see them all you can look online or at a store near you.
